This invention relates to a process of mixing liquids mechanically and uniformly in certain ratios or percentages which are fixed after adjustment but which may be adjusted to vary said ratios or percentages as desired.

The invention is capable of use in many relations but is particularly valuable in the sterilization field where it is frequently de sired to introduce disinfecting or germicidal solutions into water at the rate of a very small percentage of the germicide to a very large percentage of water.

lVhile the principles of the invention may be employed in conjunction with municipal Water plants, swimming pools, and the like,

I contemplate, as one very important use of the invention, its incorporation into a highly ornamental, attractive and interesting sterilizer for use on soda fountains to steri- 29 lize and disinfect the Water used to Wash the drinking glasses, spoons, dishes, and the like, there employed.

In the particular embodiment of the invention which I have shown for purpose of illustration, the sterilizer comprises a glass structure, into one compartment of which city water is discharged and from which compartment the city water is conducted to the sink or rack or other point of use; the flow of the water being used to automatically draw from a second compartment a colored disinfecting fluid or germioide in minute quantities, such for example, as one part of the germicide to one-billionth part of Water.

The device is made, in the main, of glass, so that the change of color of the water will be carried out in view of the patrons who will thereby be apprized that the establishment in question is disinfecting the Water used for washing the implements employed, and this has been found to be highly efficient in attracting trade.

In the accompanying drawing Figure 1 is a view partly in elevation and partly in section of a device constructed in accordance with the invention.

Figure 2 is an enlarged sectional view through the adjustable mixing valve hereinafter described.

In the drawing, 5 indicates a regulating valve disposed in a city Water supply line 6, and 7 indicates a conventional type of water pressure gauge. The'supply line ter-, minates in a goose neck 8, a thread 9 of which receives a packing nut 10 which bears upon a rubber or like gasket 11 and binds between said nut and an enlarged element 12 of a mixing tube 13, the web 14 of a hood 15. A reflector 16 is mounted upon the top of the hood 15 and carries an electric light 18 which aids in illuminating the interior of the compartment 19. This compartment receives the disinfecting and germ-destroy= ing liquid.

The bore of the mixing tube constitutes a part of the conduit by which the water is delivered into the mixing tube 20. The chambers l9 and 20'are separated from each other bya partition 21. An outlet pipe 22 has a baiilecone 23 disposed over its upper end and this pipe passes through the bottom of the glass receptacle24 within which the chamber 20 is located and through a base 26. Packng nuts 26 and 27 bind these parts together and compress packing washers Q8, 29 and 30m; such a way as to bring about a fluid tight oin a A Utube 31 establishes communication between. the interior of the compartment or so chamber 19 and a port 32 which leads to the bore 33 of-the mixing chamber.- The assage of the disinfecting fluid-through the U-tube and port 32 is controlled by a valve The stem of this valve is slotted, as indlcated at 35,'for the reception of a screw driver or like tool and said valve passes through a packing gland 36. The flow of the germicidal liquid through the-port'32 may bevery minutely adjusted by proper adjustment of valve 35, and by making bore 33 of the mixing tube of the shape shown, namely, downwardly flaring, the flow of the city water through said bore will draw a minute amount of the liquid through the tube 31and the port 32. The light 18 makes it possible for the patrons to see what is going onand to observe the gradual change of color which takes place between the time that the water enters compartment 20 and the time that it v finds its way out of said compartment around and beneath the bafile cone 23.

The water flows continuously into the soda fountain sink and in and about the water rack so that the dish water is continuously and automatically disinfected in order to kill trench mouth germs and all sorts of communicable diseases. The principle here shown and described is applicable to restaurants, hotels, dairies, bottling plants, municipal water plants, etc., so that any kind of drinking or wash water may be kept free from any kind of living cultures or organisms or from any source of contamination which would pollute the water by odor or otherwise.

It will be observed that the partition 21 constitutes the integral bottom of the upper portion of the glass receptacle, the interior of which constitutes chamber 19, and this bottom fits down into that part of the receptacle, the interior of which constitutes chamber 20 and may be held therein by fusing, cementing, or otherwise.

Itis to'be understood that the invention is not limited to the precise construction set forth, but that it includes within its purview whatever changes fairly come within either the terms or the spirit of the appended claims.

Having described my invention, what I claim is:

1. A device of the character described comprising a glass receptacle divided into two compartments, one-of which contains a disinfecting fluid, a water flow line passing through said compartment and discharging into the other of said compartments, said Water flow line comprising a mixing tube, and a suction line connected to the said mixing tube and receiving its supply from the chamber containing germicidal liquid, the arrangement being such that the flow of the water through the water flow line draws the germicidal solution into the water flow line.

2. A device of the character described comprising a glass receptacle divided into two compartments, one of which contains a disinfecting fluid, a water flow line passing through said compartment and discharging into the other of said compartments, said water flow line comprising a mixing tube, a suction line connected to the said mixing tube and receiving its supply from the chamber containing germicidal liquid, the arrangement being such that the flow of the water through the water flow line draws the germicidal solution into the water flow line, a discharge pipe leading from the last named compartment, and a baffle between said pipe and the water flow line.

In testimony whereof, I hereby aflix my signature. I

EDWARD DORSEY.
